Оскільки Pydantic серіалізує це на боці **Rust**, ви отримаєте значно вищу **продуктивність**, ніж якби не оголошували тип повернення.

### Не-async *функції операцій шляху* { #non-async-path-operation-functions }

Ви також можете використовувати звичайні функції `def` (без `async`) і використовувати `yield` так само.

FastAPI подбає про коректне виконання, щоб воно не блокувало цикл подій.

```

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
- Each pool expects each host in this pool has the same number of drives specified as any other host.
